Biomes
What are Biomes?
-Generalized/major types of ecosystems that broadly correspond to major
climatic regions
2 classifications of biomes:
1. Terrestrial- land based
2. Aquatic- water based
a. How are terrestrial biomes defined?
1. Average annual tempe

Introduction to the theory of evolution
Theory- broad, comprehensive explanation of a large body of information
1. has been subjected to extensive experimental testing
2. must be supported by the accumulation of a wide range of different kinds of
evidence

Descent with modification: a Darwinian View of life
What is evolution? -Change over time
a. can be small-scale changes
-ex: change in allele frequencies in a population
b. can be alrge-scale changes
-ex: descent of different species from a common ancestor

Ecosystem Ecology
What is an ecosystem?
-all organisms + non-living environment in an area
In an ecosystem
a. Biotic components- living
b. abiotic components- non-living
Ecosystem Ecology: Ecosystem ecology studies the interaction between the biotic and a

The Evolution of Populations- Part 1
a. gene- sections of DNA that code for production of proteins
b. allele- alternate forms of the same gene
c. gene pool- all the alleles of all the genes in a population
d. haploid- an organism or cell with only one cop

Introduction to ecology and the biosphere- Part 1 (areas of ecological study and climate)
What is Ecology?
a. Ecology-the study of interactions between organisms and between organisms and
their environment
b. ecological patterns and processes can take pla

Community Ecology
Population- group of same species living in same area at the same time
Community- populations of different species interact
Community Ecology- the study of patterns and processes involving at least two species at
a particular location

Descent with modification- part 2- evidence for evolution
Theory of evolution
a. States:
1. species change through time
2. species related by common ancestry
b. evidence should fall into one of these two categories
Evidence of change through time: Fossils

The Evolution of Populations- Part 1
a. gene- sections of DNA that code for production of proteins

Principles of Biology I Advice

Showing 1 to 2 of 2

Dr. Krueger is an excellent professor who loves talking about her passion, biology! She gives plenty of visual aids during her lectures which can help students remember what was talked about come time for the exams.

Course highlights:

Specifically in her class, I enjoyed covering insects. She brought in display cases of different insects that the class got to view, which gave a nice break from writing notes.

Hours per week:

3-5 hours

Advice for students:

Go to SI sessions! They really help.

| Would highly recommend.

Pretty easy, overall.

Course Overview:

Love this course!!! Perfect Freshmen/entry Bio course. Not hard, but get the info you need. Recommend x10000

Course highlights:

Learn a range of information about diversity, evolution, and ecology. Notes are handwritten so come to class!! Tests are all fill in the blank, but just do the study guides and you'll succeed!
